A Two-Century-Old Shadow Makes Four Light Knots
NTU Singapore generated four kinds of optical skyrmion in one Poisson spot using a laser and a small circular disc instead of a fabricated metamaterial.
Summary
NTU Singapore generated four kinds of optical skyrmion in one Poisson spot using a laser and a small circular disc instead of a fabricated metamaterial.
Nanyang Technological University researchers report that a classic diffraction effect can generate optical skyrmions, stable topological patterns in the properties of light. Shining a laser around a circular obstruction produced spin, Stokes, electric-field, and magnetic-field skyrmions within one Poisson spot. The Optica result offers a simpler research platform than engineered metamaterials. Proposed uses in storage, communications, and computing remain prospective; the demonstrated advance is accessible generation and comparison of the light structures.
